(Disclaimer: This post is sympathetic to a certain subset of theists. I am not myself a theist, nor have I ever been one. I do not intend to justify all varieties of theism, nor do I intend to justify much in the way of common theistic behavior.)
I'm not adopted. You all believe me, right? How do you think I came by this information, that you're confident in my statement? The obvious and correct answer is that my parents told me so1. Why do I believe them? Well, they would be in a position to know the answer, and they have been generally honest and sincere in their statements to me. A false belief on the subject could be hazardous to me, if I report inaccurate family history to physicians, and I believe that my parents have my safety in mind. I know of the existence of adopted people; the possibility isn't completely absent from my mind - but I believe quite confidently that I am not among those people, because my parents say otherwise.
Now let's consider another example. I have a friend who plans to name her first daughter Wednesday. Wednesday will also not be adopted, but that isn't the part of the example that is important: Wednesday will grow up in Provo, Utah, in a Mormon family in a Mormon community with Mormon friends, classmates, and neighbors, attending an LDS church every week and reading scripture and participating in church activities. It is overwhelmingly likely that she will believe the doctrines of the LDS church, because not only her parents, but virtually everyone she knows will reinforce these beliefs in her. Given the particular nuances of Mormonism as opposed to other forms of Christianity, Wednesday will also be regularly informed that several of these people are in a position to have special knowledge on the subject via direct prayer-derived evidence2 - in much the same way that her parents will have special knowledge of her non-adopted status via direct experience when she wasn't in a state suitable to notice or remember the events. Also, a false belief on the subject could have all kinds of bad consequences - if the Muslims are right, for instance, no doubt Hell awaits Wednesday and her family - so if she also correctly assumes that her parents have her best interests at heart, she'll assume they would do their best to give her accurate information.
Atheism tends to be treated as an open-and-shut case here and in other intellectually sophisticated venues, but is that fair? What about Wednesday? What would have to happen to her to get her to give up those beliefs? Well, for starters, she'd have to dramatically change her opinion of her family. Her parents care enough about honesty that they are already planning not to deceive her about Santa Claus - should she believe that they're liars? They're both college-educated, clever people, who read a lot and think carefully about (some) things - should she believe that they're fools? They've traveled around the world and have friends like me who are, vocally, non-Mormons and even non-Christians - should she believe that her parents have not been exposed to other ideas?
Would giving up her religion help Wednesday win? I don't think her family would outright reject her for it, but it would definitely strain those valued relationships, and some of the aforementioned friends, classmates, and neighbors would certainly react badly. It doesn't seem that it would make her any richer, happier, more successful - especially if she carries on living in Utah3. (I reject out of hand the idea that she should deconvert in the closet and systematically lie to everyone she knows.) It would make her right. And that would be all it would do - if she were lucky.
Is it really essential that, as a community, we exclude or dismiss or reflexively criticize theists who are good at partitioning, who like and are good at rational reasoning in every other sphere - and who just have higher priorities than being right? I have priorities that I'd probably put ahead of being right, too; I'm just not in a position where I really have to choose between "keeping my friends and being right", "feeling at home and being right", "eating this week and being right". That's my luck, not my cleverness, at work.
When Wednesday has been born and has learned to read, it would be nice if there were a place for her here.
1I have other evidence - I have inherited some physical characteristics from my parents and have seen my birth certificate - but the point is that this is something I would take their word for even if I didn't take after them very strongly and had never seen the documentation.
2Mormons believe in direct revelation, and they also believe that priesthood authorities are entitled to receive revelations for those over whom they have said authority (e.g. fathers for their children, husbands for their wives, etc.).
3I have lived in Salt Lake City, and during this time was, as always, openly an atheist. Everyone was tolerant of me, but I do not think it improved my situation in any way.
[Disclaimer: I'm having a pretty strong negative emotional reaction to this post, and much of this thread, but I'm really trying to give you the benefit of the doubt; I apologize if I come off as snippy.]
No, it makes sense in any case. Even if there's a god. Even if that god is omniscient. Even if that god is benevolent. And even is that god is perfectly rational!!
There's a difference between "rational" and "ethical". (By your argument, Satan could not possibly be rational... is that your belief?) There's a difference between "rational" and "logically internally consistent". The mentally ill can be logically internally consistent, but that is not what we mean by "rational".
Let me ask you again: why are you here? I don't intend it as a rhetorical equivalent to "fuck off"... I'm honestly asking: what do you hope to get out of this?
I don't know if you read Eliezer's recent Epistle to the New York Less Wrongians, but I'd like to highlight a few of the items in the list of things rationality is about:
These are what rationality are for me. (The second point, in particular, is what I was trying to say when I spoke of "logic games".) And these things are not dependent on there not being a god! (In fact, if you want to convince me that there is a god (in another thread, please!), these points are the way to do it.)
Are you here to say 'oops' on occasion? Are you here to look for the truth (or are you convinced that you've already found it)?
Rationality, the set of tools for for examining and changing our beliefs, necessarily must be more basic than any of your beliefs. Otherwise, it isn't rationality... just logic games.
I'm here because I want to be Less Wrong! And that means changing my beliefs, and not to be more in-line with everyone else here! For example, my most recent 'oops':
I recently adopted a vegan lifestyle, saying "oops! I shouldn't be eating animals". (While I may, for the sake of brevity, refer to myself as 'vegan', in my mind I see myself as 'living a vegan lifestyle'. I've even quipped, "No, I'm not vegan, I just live like one.") I don't know if there are any other vegans here, but I've never seen any posts claiming it to be virtuous, and I assume it is a minority view here.
But it was a process of rationality that led me to making the lifestyle choice. While I may have, someday, come to the same conclusions on my own, it was my exposure to Less Wrong that helped me to "shut up and multiply", to overcome my biases and fears, and just say 'oops'.
Even the name of this site helped! Just as this isn't "BeingRight.com", the issue for me was clearer once I viewed (my own personal take on) veganism not as "the Right choice", but as "Less Animals": I don't claim to be right, just a bit less wrong that I was being before.
Sorry, that was a bit of a tangent... but do you see what I mean? That's what I'm here for. Is that what you're here for?
